A series of hand and wrist radiographs was assessed manually by two individuals and by a fully automated computer system for determining bone age. Assessments were repeated after 1 month to determine variability between and within the methods of bone age assessment. There was slight intra-observer variation, but complete reproducibility when assessments were made by computer. The variation between the human assessors was less than that between human and computer assessments. The difference between overall maturity scores made by the human observer and the computer system was, however, acceptably small, and the majority of assessments were the same. It is concluded this computer system for assessing bone age in normal children is reliable and accurate, but that it needs to be validated against a much larger set of radiographs.
两名人员和一个全自动计算机系统对手部和腕部的一系列X光片进行了手动评估，以确定骨龄。1个月后重复评估，以确定骨龄评估方法之间和方法内部的变异性。观察者内部存在轻微差异，但计算机进行评估时具有完全可重复性。人类评估者之间的差异小于人类与计算机评估之间的差异。然而，人类观察者和计算机系统给出的总体成熟度评分之间的差异小到可以接受，并且大多数评估结果相同。结论是，这种用于评估正常儿童骨龄的计算机系统可靠且准确，但需要根据更多的X光片进行验证。
